what is the best thing to do after gladioli have finished flowering, lift & dry out or leave them in & feed the bulb for next year. the bulbs were planted on 2" of horticultural grit & have done really well.

I have always let mine die back as much as possible, cutting off any remaining foliage and then lifted before the first frost and allowed them to dry out and storing before replanting again the following year.
